hi, just replaced the lower unit.my new prop shaft is non threaded. the new shaft also has a slot at the end, similar to a fw key slot but opened at the end. my manual shows a non threaded prop shaft but no slot. the manual calls for #305294 prop nut and a 304576 thrust washer.
my old prop and my 58 sporttwin have the threaded configuration. so thats all that ive seen . does the non threaded shaft sound like the original?(308421).
